I was updating the PHP version to the newest in my CentOS server, following this guide step by step. When I finally get to install PHP, I get the following error.
sudo yum install php53 php53-cli php53-common php53-devel php53-gd
-bash: sudo: command not found
Or just
yum install php53 php53-cli php53-common php53-devel php53-gd
-bash: yum: command not found
Can anyone help me?
(sorry for my bad english)
